Algae from Southern Coast

N BALAKRISHNAN NAIR, V SOBHA & M ARUNACHALAM Department of Aquatic Biology & Fisheries, University of Kerala, Trivandrum 695007 Received 21 November 1981; revised received 25 January 1982 ,. Algal colIections were made from 10localities along the Ketala coast, and 44 species belonging to 29 genera of 18families were recorded. Algal colIections from different stations in were also made.

While some information about the marine algae from An annotated systematic list of algae collected from Gujaratl-4, MaharashtraS-16, and Goa17-18 coasts different stations along the Kerala coast and the is available, very little is known about this ecological factors like substratum, temperature, economically important group from the coasts of salinity and dissolved oxygen of the region from wher.e Karnataka and Kerala. With a view to filling up this algae were collected are given in Table 1. Algal lacuna an effort has been made to collect (8 March - 31 distribution in the Ashtamudi lake is shown in Fig.1. Oct 1981)algae and sea grasses from selected localities According to Krishnamurthy and Joshi19, 492 algal along the Kerala coast. As many as 44-species of algae species belonging to 168 genera included under 54 and 2 species of sea grasses have been collected and families occur along the coasts of . Srinivasan20 identified. Of these 14 species were from the estuarine recorded 275 species belonging to 134 genera along the habitat. Since this is the first comprehensive report of West Coast. Untawale et al.16 reported 94 species algae from this coast, a classified list of species collected included under 51 genera and 30 families from the during the survey is presented. With a view to finding coast of Maharashtra. Present collections from 10 out the nature of distribution of algae along the shores localities revealed the existence of 44 sPecies belonging of the back-waters collection (8-17 March 1981) was to 29 genera of 18 families. Despite the fact that these made in the Ashtamudi lake. collections are not veryexhaustive it is noteworthy that
